UNITED STATES PATENT OFFICE.

ELECTRIC RADIATOR.

Application filed April 18, 1927. Serial No. 183,516.

My invention relates to radiators and more particularly to the typeknown as electric radiators.

It has for its objects to provide a more inexpensive radiation than hasheretofore been had; to provide convenient radiation means easilyadaptable for portable use; to provide a new and novel combinationembodying electrical conduit encased in pow- 1 dered substance,producing maximum heat storage with minimum current consuniption andextended heat radiation over a pro longed period after the electricalcurrent has been shut off; to provide a new and novel combinationembodying a meta-l radiator case adaptable as a container for generatingand radiating electrical heat, and to provide the various otheradvantages and results made evident from the following specification.

I accomplish the objects of my invention as shown in the accompanyingdrawings, which form a part of this specitication, and in which Figure lshows an electrical resistance element, utilized in and encased by eachof the radiator units shownin Figure 2, one or more of which units areconnected to furnish a completed radiator of any given size. Figure 3shows a top view of my assembled radiator. Figure e shows an end viewthereof.

Referring again to the drawings (Figure l), A shows the joint holdingrod and ref turn electrical current conduit adapted to suppoit theresistance element in position within the radiator unit. B shows aniusulation plate attached by the nuts C and D to the threaded end of therod A opposite its end (also threaded) carryingthe return wire to thesource of electrical energy. to which it is attached by the nuts K andL.

E shows the insulation material, preferably porcelain, separating therod A from the heating coil F, one end of which is attached to the rod Aby the nuts C andG, and its opposite end attached to the contact H whichencircles the insulation E. To the Contact H is connected the lead wireI from the source of electrica-i energy.

Referring again to Figure 2, IWI shows the radiator units, a portion ofone being cut away to disclose the electrical resistance elementpositioned therein. N shows the cy- .iindrical connection joining theradiator units, also serving as a wire conduit and switch container. asdisclosed in its cut awa Y portions. O shows a powdered substance ofheat retaining qualities with which the radiator units are iilled, theresistance element being embedded therein.

Referring again to Figure 4, P shows the position of the controllingswitch, by means of which the electrical current is turned on and off.

Similar letters of reference refer to similar parts throughout thevarious views.

iVhile I have illustrated and described a preferred construction forcarrying my invention into eitect, this is capable of variation ormodification wit-hout departing from the spirit of the invention. Itherefore do not wish to be limited to the exact details of constructionherein set forth, but desire to avail myself of such variations andmodifications as come within the scope of the appended claim.

Havin' thus described my invention I claim as new and desiie to secureby Letters Patent of the United States of America:

In an electrical heating apparatus, the combination of a plurality ofresistance elements each having a supporting rod and an insulating plateon the end of each rod, a plurality of vertical, hollow radiator unitseach of which is adapted to receive a resistance element therein, saidinsulating plates adapted. to position said elements therewithin, aplurality of connecting conduits one arranged between and at the tops oteach of the radiator rinitis and adapted to receive the wiringconnections from the rods and coils of the several resistance elements,and an end conduit section carrying a switch and to which all of saidwires are led for the purpose deiined.

In testimony whereof, I aiiix my signature.

AUGUSTUS M. NICKERSON
